The large-scale power system that emerged in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, transmission, transformation, distribution and power consumption. Power cables are cables used to transmit and distribute electric energy. They are often used in urban underground power grids, lead-out lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the trunk lines of the power system. Power workers generally work in the field.

[0011] In some embodiments, the circumferential outer walls of the two limit rods are fixedly connected to limit blocks, and the two limit rods are sleeved with return springs, and the two ends of the return springs are respectively fixedly connected to the limit blocks and the square blocks.

[0012] In some embodiments, a threaded hole is opened on the top of the chassis, a threaded column is screwed into the threaded hole, a fixing column is fixedly connected to the top of the threaded column, and a steel ball is fixedly connected to the top of the fixing column.

[0013] In some embodiments, an outer tube is sleeved on the circumferential outer wall of the fixing column, a tray is fixedly connected to the circumferential outer wall of the outer tube, a sink is provided on the top inner wall of the outer tube, and the sink is adapted to the steel ball.

[0014] In some embodiments, a plurality of self-locking universal wheels are installed at the bottom of the chassis.

[0015] Compared with the prior art, the present invention has the following significant advantages:
